A double-blind, randomized, crossover study was conducted to compare the efficacy and safety of high-dose dexamethasone (Protocol D) with a combination of dexamethasone, metoclopramide and diphenhydramine (Protocol DMD) in the management of chemotherapy-induced nausea and vomiting in cancer patients. All entered patients had received no prior chemotherapy. During the study chemotherapy was administered on an inpatient basis. The majority of patients (94%) were treated with cytotoxic drugs of significant emetogenic activity and 40% of the study group received cis-platin-containing combinations. Of the 60 evaluable patients, complete antinausea and antivomiting effects of D were observed in 30 (50%) and 34 (57%), respectively and of DMD in 17 (28%) and 26 patients (43%) respectively. The difference was not statistically significant (P = 0.09 and 0.24, respectively). Lack of significant difference between the two regimens was demonstrated irrespective of the administered cytotoxic drugs. The DMD protocol caused more adverse reactions than D. While 27 patients (45%) experienced no side effects from D, only 14 (24%) remained free of complications due to DMD (P = 0.001). Furthermore, DMD produced more sedation, insomnia, headache, diaphoresis, dizziness and diarrhoea than the D regimen. In addition it gave rise to more adverse effects on appetite and activity. Upon direct questioning, 37 patients (62%) expressed a preference for D, 14 (23%) preferred DMD and 9 (15%) found no difference between the two regimens. We conclude that, while the short DMD protocol has an antiemetic activity equivalent in its effectiveness to D, its associated adverse reactions would minimize its usefulness. Therefore, further investigations should be conducted to find a safer and more potent combination of antiemetics suitable for therapy in an outpatient setting.

Sleep-related respiratory disturbances (SRD) in patients with muscle diseases may have significant clinical implications, because the patients frequently die at night. The aims of the study were to :1) assess the presence and severity of sleep-related respiratory disturbances in patients with Duchenne muscular distrophy (DMD); and 2) investigate the relationship of sleep-related respiratory disturbances to daytime symptoms and pulmonary function. We studied six clinically stable patients with Duchenne muscular dystrophy, mean age (+/- SD) 18 +/- 2 yrs. Vital capacity was 27 +/- 19% of predicted and daytime arterial oxygen tension (PaO2) was 10.9 +/- 1 kPa (range 8.9-12.4 kPa). The presence of daytime somnolence, insomnia, headache, nightmares and/or snoring was recorded. Four patients (67%) showed symptoms that suggest sleep-related respiratory disturbances. At night, the apnoea-hypopnoea index (AHI) was 11 +/- 6. The patients with more symptoms during the daytime had the highest AHI scores. Most of the apnoeas (85%) were central, particularly during rapid eye movement (REM) sleep. Sleep architecture was well-preserved. Arterial desaturation (> 5% below baseline) occurred during 25 +/- 23% of total time. AHI correlated with daytime PaO2, and AHI in REM sleep correlated with age. A stepwise multivariate analysis showed that PaO2 and, to some extent, the degree of airflow obstruction were significantly correlated with AHI. We conclude that sleep-related respiratory disturbance are frequently present in patients with Duchenne muscular dystrophy. Therefore, physicians should look for symptoms related to sleep-related respiratory disturbances in these patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Individuals with Duchenne muscular dystrophy (DMD) have evolving sleep and respiratory pathophysiology over their lifetimes. Across the lifespan of DMD, various sleep-related breathing disorders (SRBD) have been described, including obstructive sleep apnea, central sleep apnea, and nocturnal hypoventilation. In addition to SRBD, individuals with DMD can be affected by insomnia, chronic pain and other factors interfering with sleep quality, and daytime somnolence. The natural progression of DMD pathophysiology has changed with the introduction of therapies for downstream pathologic pathways and will continue to evolve with the development of therapies that target function and expression of dystrophin.
